10/25 = 2/5
Divide by 5 to get simplest form
You can convert 1000 to hex and see how many digits that requires:

So every integer below 1000 needs up to 3 digits.
Alternatively, we know that

, and that

requires

digits in its hex representation (e.g.

). Taking the logarithm, we get

, and adding 1 gives the number of digits needed to represent

. Similarly,
What is the domain and range for {(0,-5),(1,3),(2,2),(0,4)(-5,6),(3,4)}
Inga [223]
The domain are the x values and the range are the y values.
Domain {0, 1, 2, -5, 3}
Range {-5, 3, 2, 4, 6}
Note: you do not repeat a number if it is already in the domain or range.
Look at the slope. if the slopes are the same, the two lines are parallel. if the slopes are negative reciprocals, the lines are perpendicular. otherwise, neither, the two lines will intersect.
6y=x+9
y=(1/6)x+(9/6)
the slope is 1/6, while the second line has a slope of 7, so the two lines have different slopes, so choice D is correct.
